(It is not very busy, but we are short-staffed so everyone is working hard. My manager helps me bag a particularly big order.)

Me: “Okay, ma’am, I believe my manager and I got all of your food. But, just in case, let me go over your receipt again.”

Customer: “Okay.”

(We go over the receipt together and find everything is correct.)

Customer: “Thank you, dear.”

Me: “You are very welcome, ma’am!”

Manager: “Did you go over her order again before you let her leave?”

Me: “Yes!”

(Five minutes later a man walks in brandishing a receipt and yelling.)

Man: “You idiots messed up my order!”

Me: “I’m sorry, sir. Can I help you?”

Man: “Yeah, I came through drive-thru and didn’t get half of my order!”

(I look over the receipt and see it is from the previous customer that I just helped.)

Me: “Sir, I don’t think this is your order. I packed this order a few minutes ago, and it was for a lady on counter.”

Man: “How dare you accuse me of lying! I want to talk to your manager!”

Me: “Fine.”

(The manager proceeds to tell him the same thing, but he won’t stop screaming at her. Eventually, he demands to see the store manager.)

Store Manager: “What seems to be the problem, sir?”

Man: “Look, I came through the drive-thru. This is my receipt, but your stupid employees won’t give me my food!”

Store Manager: “Well, sir, I am certain this is not your receipt.”

Man: “Oh yeah? Prove it!”

Store Manager: “Well, the top of the receipt says the order was taken from the register at the counter, which means it could not have been for a drive-thru order. And, according to the receipt, this was ‘Katie’s’ order. You don’t look like a ‘Katie.'”
